Spring Break in Miami

While in Miami over spring break, I attended a Miami Heat basketball game with my family. At halftime they brought out the cheerleaders and they performed their routine and were applauded when they were done. After they finished, they brought out a group of 15 old women to do the exact same routine as the much younger group which preceded them. They were celebrated much more loudly with a huge roar and greater applause. Were they being mocked because they were old, out of shape women? Or were there dance moves truly better than that of the previous group? I thought it was odd to see that. I wanted to hear what everyone else thought of what this.
